"In the last three decades a collection of linear supply chains has become a complex adaptive network of demand creating supply. The benefits are obvious. The risks tend to be insidious. With the 2012 National Strategy for Global Supply Chain Security and the 2013 Implementation Update on the strategy, a public-private process has been engaged for considering risks and cultivating resilience. Complex adaptive systems are not well suited to traditional security mindsets. In the natural environment resilience emerges from diversity, self-organization, and innovation. Are these characteristics appropriate to the supply chain? Can these characteristics be systematically cultivated by private and public decision-makers who influence the supply chain? This essay points to prior examples of dealing with complex adaptive systems to suggest an affirmative conclusion."
